Runs on-device · works on iPhone, Android, iPad & Mac
Or run a single test
Screen test
Fill the screen with solid colours to spot dead pixels, stuck pixels and patches.
Touch test
Drag across every cell to find dead zones, plus a multi-touch finger check.
Speaker test
Play clean tones through the left, right and both speakers to check for crackle or silence.
Mic test
Speak and watch a live level meter respond — confirms the mic is picking up sound.
Camera test
Preview the front and rear cameras live — check for blur, spots or a black frame.
Sensors test
Fire the vibration motor and tilt your phone to see the gyroscope respond live.
GPS test
Get a live location fix and see how accurate your GPS reading is.
Face/Touch ID
Confirm your device's biometric sensor — Face ID or Touch ID — is available and recognised.
Charging test
Plug in your charger and watch the live battery + charging status flip.
Flashlight test
Switch the rear LED torch on and off to confirm the flash fires.
Bluetooth test
Scan for nearby Bluetooth devices to confirm the radio is alive.

Good questions
about the test.
Is it free, is it private, does it replace a real diagnosis? The things people ask before they tap Start.
Yes — every test runs in your browser, free, with no sign-up. If a test flags something, our in-person bench diagnosis is also free; you only pay once you approve a repair quote.
No app needed. The tests use standard web features, so they run on any modern phone, tablet or laptop browser.
Never. Camera and microphone tests are processed entirely on your device for the live preview/meter — nothing is recorded, stored or sent anywhere.
No. It's a quick self-check that spots obvious symptoms. Physical damage, battery health and board-level faults need a proper bench test — which iTweak does free before any repair.
